Wnt Family Member 3A (WNT3A)
- Target
- WNT3A
- Molecular classification
- Secreted signaling protein, Wnt family member
01
Overview
WNT3A is a secreted signaling protein belonging to the Wnt family, crucial for embryonic development, tissue homeostasis, and disease. It plays a pivotal role in mesoderm and neural tube formation during embryogenesis. WNT3A activates the canonical Wnt/β-catenin signaling pathway, influencing cell proliferation, apoptosis, and differentiation. Dysregulation of WNT3A can contribute to tumorigenesis. Recent research highlights its potential in regenerative medicine, particularly in nerve regeneration by enhancing Schwann cell function.

02
Mechanism of action
Activation of Wnt/β-catenin signaling pathway via Frizzled receptors and LRP5/6 co-receptor; stabilization of β-catenin and translocation to the nucleus to activate target gene transcription; activation of noncanonical pathways possible.
